You’re standing in the middle of a grassy biome with twelve obsidian-colored frames and a handful of glowing eyes, wondering why the void isn't opening. It's frustrating. Honestly, it’s one of those things in Minecraft that looks easy on paper but has one specific, annoying mechanic that trips up almost everyone the first time they try it. If you're playing in Creative Mode, you've probably realized that just plopping the blocks down in a square doesn't do anything.
The game is picky. Really picky.
If you want to know how do you build a ender portal in minecraft, you have to understand that the "front" of the block actually matters. Most blocks in Minecraft are symmetrical. These aren't. If you place them while standing outside the circle, the portal literally won't activate because the "internal" face of the frame is pointing toward a forest or a mountain instead of the center of the pool.
The Secret Geometry of the Frame
Most players just fly around and place the blocks while looking down. That's the mistake. To get a portal to actually "spark" and create that starry black texture, you need to be the center of the universe. Literally.
Stand in one spot. Don't move your feet.
You need to place three frames in front of you, turn 90 degrees, place three more, turn again, three more, and one last turn for the final three. This ensures that the invisible "front" of every single frame block is facing the center of the 3x3 space. If even one block is sideways, you're just looking at a pile of expensive rocks. You can actually see this if you look closely at the top of the frames. There are little green tabs or "decorations" on the top of the End Portal Frame. Those pixels need to be pointing toward the middle.
Why Survival Mode is Different
Now, if you’re trying to do this in Survival, I have some bad news: you can’t "build" it. Not in the traditional sense. You can't craft the frames. You can't mine them and move them. Even with a Silk Touch pickaxe, those blocks are staying exactly where Mojang put them.

In Survival, "building" the portal is more like "repairing" it. You have to find a Stronghold first. This involves throwing Eyes of Ender into the air and following them across thousands of blocks until they start diving into the dirt. Once you find the portal room—usually tucked away behind some iron bars near a silverfish spawner—you'll notice some of the frames are already filled with eyes, and some are empty.
You just need to pop the remaining Eyes of Ender into the empty slots. The orientation doesn't matter as much here because the world generator already placed the blocks correctly. You’re just the guy with the batteries.
Gathering the Materials for the Eyes
You can't have a portal without Eyes of Ender. This is where the grind happens. You need Blaze Powder and Ender Pearls.
- Kill Endermen. Lots of them. If you can find a Warped Forest in the Nether, they spawn way more frequently there.
- Go to a Nether Fortress. Find the Blaze spawner.
- Turn those Blaze Rods into powder and combine them with the pearls in your crafting grid.
Pro tip: Grab a few extra. Eyes of Ender have a nasty habit of shattering when you throw them to find the Stronghold. Nothing is worse than getting to the portal room and realizing you're one eye short because a pearl broke over a desert three miles back.
The Logic Behind the Glitchy Placements
Sometimes you do everything right and it still fails. If you’re in Creative and the portal isn't working, check the ground. The 3x3 area in the middle of the frames needs to be empty or filled with a specific liquid (though usually, just air is fine). If there are tall grass blades or weird half-slabs in that 3x3 gap, the portal might get confused.
Also, don't put blocks in the corners. A proper End Portal is a 5x5 square with the corners missing. If you put blocks in those four corner spots, it won't break the portal, but it's a waste of space and makes it look like a beginner built it. Real pros keep it as a floating 12-block ring.
Speedrunning Tactics and World Seeds
If you're watching Dream or any of the top speedrunners, you'll notice they don't even look at the frames when they place them. They use "blind" placements based on muscle memory. But for the rest of us? Take your time.

If you're looking for a shortcut, there are specific "12-eye" seeds. These are incredibly rare world seeds where the game's random number generator accidentally fills all 12 frames in a Stronghold automatically. The odds are roughly one in a trillion. For everyone else, you're going to be hunting Blazes.
Final Steps for Activation
Once the frames are down and you're sure they're facing inward, hold your Eyes of Ender. Walk around the outside (don't fall in early!) and right-click each frame. The moment the 12th eye clicks in, the center will turn into a black void.
Don't jump in immediately.
Make sure you have your bed nearby. Set your spawn point. If you jump into that portal and the Ender Dragon knocks you off the obsidian platform into the void, you’re losing everything. Having a bed right next to the portal ensures you can get back in the fight within seconds.
Check your armor one last time. Is it Diamond? Enchanted? Do you have a water bucket? Good. Now you're ready to actually use the thing you just built.
Next Steps for Your Journey
To ensure you don't lose your gear immediately upon entering the End, follow these three preparation steps:
- Craft a Potion of Slow Falling: Use Phantom Membranes to brew these; they are life-savers if the Dragon flings you into the air.
- Inventory Check: Bring at least two stacks of "bridgeable" blocks (cobblestone or dirt) because the portal often spawns you on a platform away from the main island.
- Bed Setup: Place a bed in the Stronghold portal room and right-click it to set your respawn point. If you die in the End, you’ll wake up right next to the portal instead of back at your original world spawn.
Once you enter the void, your primary goal is to destroy the End Crystals on top of the obsidian towers before even attempting to hit the dragon. Without doing that, she will simply heal all the damage you deal. Use a bow or snowballs to snip the crystals from the ground.
